Narrative:
I was pilot flying on today's flight. We were given runway 3L for takeoff with the new 'sndrs 1' RNAV departure. Pushback was normal; we followed all of the standard procedures. We taxied out of the ramp and contacted ground. They advised us that they changed the departing runway from 3L to 4R/Y2. So I went back and did the runway change item looked at the new SID profile and completed the rest of the checklists. We continue taxing down Y until Y2 where we were cleared for takeoff via the SID. Captain gave me the controls and I performed the takeoff. Once we got airborne we switched to departure and they told us to 'climb and maintain 17;000 feet' so the captain bugs 17;000 as I was hand flying the departure. We continued the departure until somewhere between 'ferrm' & 'averl' we got a traffic advisory aural; at this time I am still hand flying the airplane and we were climbing through 8;000 feet. At that point ATC advises us to stop our climb and maintain 9;000 feet. So I lowered the nose and turned off the flight director as I decreasing our climb rate and captured 9;000 feet. Once we were established ATC informed us that we need to call the tower once we land. Captain and I looked at each other as we were very confused; nonetheless he asked ATC what we did wrong and ATC said that we missed our altitude restrictions at ferrm at or below 6; and averl at or below 7 even though we were told to climb and maintain 17;000 feet.I think there were several factors that caused this deviation. Some contributing factors includes the SID being brand new and neither I nor the captain have flown this departure. Also I should have briefed the SID a little bit more in detail once they switched runways on us. Most importantly there was a breakdown in communication between us and ATC. We were told to maintain 7;000 feet on the ground but once we got airborne we were assigned to climb and maintain 17;000 feet. We should have asked ATC if the other altitude restrictions still applied or not. It's safe to say that both of us thought we were no longer required to comply with the altitude restrictions so we flew it like all the other departures out of dtw and bugged the newly assigned altitude of 17;000.
